Virtual Planetarium Show for Kids: Turning of the Seasons

Winter does not officially start until later this month, but the weather is rapidly changing. What do astronomers mean when they say that Northern Hemisphere Winter starts at 5:02am on December 21? Turns out it has nothing to do with the weather and everything to do with geometry.

Just like programs in the Planetarium, we’ll be able to take questions—this time through chat and comments. Recommended for ages 6–10. Please register only once per household.
